CAIPED NAIL AND TACK.

Application filed November 21, 1921. Serial No. 516,613.

;- To all'whom'it may concern: a

Be it known that I, Lnwrs DANIEL, a citizen of the United States,.and aresident of Newport, in the county of Campbell and State of Kentucky,have invented certain .-.new and useful Improvements in Capped Nails andTacks, of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming part of thisspecification.

My invention relates to nails and tacks which have secured thereon capsor button heads, which nails and tacks are used in various instanceswhere it is desired to providea button for a fastener, or the like.

It is'the object of my invention toprovide such an article which can beinexpensively manufactured, and which possesses the desiredcharacteristics of appearance and strength necessary for a marketableproduct of the nature set forth.

In the manufacture of special heads, such asbuttons and the like fornails, the manufacturing cost enters very largely into consideration. Inthe past, to place a suitable button on the end of a nail or tackrequired operations of trimming and drilling, which required'specialmanipulation of the small piecesinaking' up the completed article, andwhile this could be automatically done in large part, it requiredexpensive machinery and considerably more time for each piece than wastruly economical.

According to my invention, the pieces used are stamped out and withouttrimming,

dropped onto the usual headed tack or nail ofcommerce and clamped intoplace.

. These. objects I accomplish by that certain construction andarrangement of parts to be hereinafter more specifically pointed out andclaimed, wherein a very economical manufacturing process may beemployed.

In the drawings,

a Figure 1 is a side elevationof a' completed button headed tack.

Figure 2 is a like view of the tackbefore the cap is placed thereon.

Figure 3 is a perspective view of the sim plest form of bell used inmaking the cap. Figure 4. is a perspective view of the top i piece ofthe cap.

Figure 9 is a perspective View of the parts of a third form of nail.

Figure 10 is a central longitudinal section through the parts shown inFigure 1.

Referring first to the simpler form of capped tack, it will be notedthat I employ the tack lhaving the usual head 2, which as in the usualform of tack is formed by a die opelpation on the piece of wire formingthe tac Such tacks are the usual article of coinmerce and purchasable atalow price or readily manufactured by fully automatic machinery, at ahigh rate of speed.

I provide a metal stamping having a belllike shape as at 3, and splitlips 4 at the expanded end, with the apex of the bell formed with a hole5 to slip over the shank of the tack. I also provide a top piece of fiatbody 6 and a flange 7, which in the original piece extends downwardlyfrom the body.

In assembling the article, the tack is dropped into the bell on asuitable multiple unit machine with the head lying within the bell,which is of a size at the base of the lips to snugly receive it. The toppiece is then dropped onto the assembly and pressed down and the flangeturned under,which forces the head of the tack firmly into the seat ofthe bell and engages the head around the lips of the bell, drawing saidlips to gether snugly around the head of the tack.

The article is then complete, except for enameling, if desired, andthere are no parts 'to' be injured by baking the articles after dippingin enamel.

The entire button thus formed is quite low and perfectly tight, andhammer blows on the top piece will not injure the assembly as the headofthe tack itself receives these blows and relieves the bell of anystrain.

There are no parts to be trimmed or smoothed off, as the only edgesexposed are formed by bending the metal of the top piece and bell,around their respective forms.

In m flikingthe double button head for a nail or tack, I employ a nailhaving a shank 8 and head 9, same being again a cheap article ofcommerce. I then form a double bell having a body 10 and lips 11, 11, ateach end, which turn outwardly from the tubular or body ortion of thedouble bell.

I a so provide two end pieces similar to the one top piece of the firstmodification, as at 12 andl3, the end piece 12 having a hole therein tosli over the shank of the nail.

In assemb ing the article, the bell and the lower end piece 12 are firstplaced together and the end piece crimped over the lips of the bell byfolding inwardly the flange 12 thereof. The nail is then dropped intotheother end of the hell with the shank passing through the hole in thepiece 12.

The top piece 13 is then dropped on and driven down'and the flangefolded in as at 13. The head'of the nail is thus firmly seated in theupper end of the bell where the lips start to swell and. the folding orcrimping in of the flange of the to holds the lips firmly around the heaHere again the head of the nail takes the'blows necessary for drivingdown the piece article and there is no trimming of parts necessary toeffect a finished article of great strength and perfect smoothness atall exposed or working surfaces.

In addition to the double bell formation in making up the ca ped nail, Imay also proceed as follows: igure 9) The nail 14 with the head 15 isused as in the second instance, and the bell or fitting has a tubularbody 16 with lips 17 at the lower end, but cylindrical or substantiallyso at 1 the top. The cap 18, similar to the caps already described, iscrimped over the head of the nail with its inner edge not quite meetingthe nail shank below the head.

The lower cap 19, similar to the piece 12,

is crimped over the lips 17 and the nail forced down through'the body16, and the hole in the cap 19. This willforce the upper edgeof the body16 into the space between the flange and head of the cap 18 tubular bodyand the cap 18 are arranged of the head of the-tack or nail used, and"so that the forcing of the nail downwardly into the said body will makethe tight .fit

last above noted. v p

It is obvious that by confining the size likewise controlling the sizeof the body portion of the bell as'distinguished from ton thereon,comprisin tubular body, and'a bell-shaped crest, with the lips thereof,I can make up a capped nail or tack with the desired amount of depthfrom the shoulder formed on the shank of the nail to the top of the capor button.

Having thus described my invention,

the split edges 01 said first mentioned piece.

2. In combination with a headed tack or nail or the like, a piece havina body por tion oit tubular nature expand ed at the/up per end to form aseat for the head of said tack or nail, with a portion of the piece extending below said seat to form the shank of a button, and a top piecehaving a flange thereon, said piece being adapted to engage over thehead of said tack'or nail, with the flange bent inwardly around ittoengage the expanded edges "of the first mentioned piece.-

3. In combination with a headed tack or nail or the'like, a means forforming a but a piece having a the lips :l'orming said bell-shapedorestre viding a seat for the head of the nai or tack, and a top piece shapedto fit smoothly over the said head andhaving a flange adapted to engageover the said lips and a clamp said first mentioned piece firmly inposition, as and for the purpose described.

4. In combination with a headed tack or nail or the like, a means forforminga double headed button thereon, comprising a piece having atubular body, and a cap secured thereon at its lower edge with said;

body formed out to form a seat for the head of the nail or tack,andadapted. to slide into position over the shank of the same, and a topcap adapted to engage over the head of the tack and firmly engage overthe formed-out portion of the first mentioned piece. '3

5. In combination with a headed-tack or nail or the like, a meansiorforminga double headed button thereon, comprising a tubular piece havingexpanded upperland lower edges, said expanded edges being split to formlips, an apertured'cap adapted to slide over the shank. of thetack ornail, said cap being provided with a ufiange turned inwardly overthelower expanded edges oit'the above mentioned iece,-aiid another capadapted to fit over't ahead of the tack or nail and having a fiangeadapted to be turnedinwardly beneath the' head,

and over the upperexpanded edgesofthe i a I30 first mentioned piece.

6. In combination with aheaded tack or head thereof, and-a top capadapted to ennailror the like, a means for forming a gage over the headof the nail having a double headed button thereon, comprisinga flangeformed inwardly under the head and 10 piecehaving a tubular body and capseengaging over the upper end of the tubular 5 cured thereon at itslower edge, with said body.

body adapted to slide into position over the v shank of the nail andabut the sides of the LEWIS DANIEL.
